How to add two decimals using python

The following example is for the user to input two numbers and calculate the sum of two decimals:

Example (Python 3.0) (Recommended learning: Python video tutorial)

# -*- coding: UTF-8 -*-
 
# Filename : test.py
# author by : www.runoob.com
 
# 用户输入数字
num1 = input('输入第一个数字：')
num2 = input('输入第二个数字：')
 
# 求和
sum = float(num1) + float(num2)
 
# 显示计算结果
print('数字 {0} 和 {1} 相加结果为： {2}'.format(num1, num2, sum))

The output result of executing the above code is:

输入第一个数字：1.5
输入第二个数字：2.5
数字 1.5 和 2.5 相加结果为： 4.0

In this example, we use user input Sum two numbers. The built-in function input() is used to obtain user input. input() returns a string, so we need to use the float() method to convert the string into a number.

For two-number operations, we use the plus sign ( ) operator for summation. In addition, there are also the minus sign (-), the multiplication sign (*), the division sign (/), and the floor division (// ) or remainder (%).
